1. Technical Field
The present disclosure relates to an electronic device and a method for starting up the electronic device.
2. Description of Related Art
Portable electronic device such as a mobile phone has several states, for example, a working state and a sleep state. When the mobile phone is changed from the sleep state to the working state, a user needs to hold the mobile phone by one hand, and operate the mobile phone with the other hand. However, when the user is using one hand on other matter, it is difficult to operate the mobile phone with only one hand.
Therefore, there is a need for improvement in the art.
Many aspects of the embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean “at least one.”
In general, the word “module,” as used herein, refers to logic embodied in hardware or firmware, or to a collection of software instructions, written in a programming language such as Java, C, or assembly. One or more software instructions in the modules may be embedded in firmware, such as in an erasable-programmable read-only memory (EPROM). The modules described herein may be implemented as either software and/or hardware modules and may be stored in any type of non-transitory computer-readable medium or other storage device. Some non-limiting examples of non-transitory computer-readable media are compact discs (CDs), digital versatile discs (DVDs), Blue-Ray discs, Flash memory, and hard disk drives.
The electronic device 10 includes a processing unit 101, a random access memory (RAM) 102, a read only memory (ROM) 103 and a display 104. The processing unit 101 is coupled to the RAM 102, the ROM 103 and the display 104. The processing unit 101 may include one or more processors that provide the processing capability to execute the operating system, programs, user and application interfaces.
The electronic device 10 has a substantially rectangular body. The electronic device 10 includes a front surface 11 and a side surface 12 substantially perpendicular to the front surface 11. The display 104 is located in a middle of the front surface 11 for displaying information. In another embodiment, the display 104 can also be a touch panel for inputting information. A first sensing area 112 is located in the front surface 11 above the display 104. A second sensing area 122 is located in the side surface 12. In one embodiment, the side surface 12 is located at a top side of the electronic device 10. In another embodiment, the side surface 12 can also be located at a left side or a right side of the electronic device 10. The first sensing area 112 can also be located in the top side, the left side or the right side of the electronic device 10.
The first sensing area 112 and the second sensing area 122 are coupled to the processing unit 101. The first sensing area 112 and the second sensing area 122 are configured to detect finger motions of a user (not shown) by detecting whether illumination of light to the first and second sensing areas 112, 122 is blocked by fingers of a hand of a user of the electronic device 10. The first sensing area 112 and the second sensing area 122 are substantially formed by carbon nano tube materials which are mounted on the electronic device 10. Therefore, a thickness of the first sensing area 112 and a thickness of the second sensing area 122 are reduced. When the first sensing area 112 and the second sensing area 122 are covered, illuminations of light detected by the first sensing area 112 and the second sensing area 122 are decreased.
When the electronic device 10 is changed from a sleeping state to a working state, the thumb 21 is moved above the first sensing area 112 to cover the first sensing area 112, and the index finger 22 is moved above the second sensing area 122 to cover the second sensing area 122. When the thumb 21 covers the first sensing area 112 and the index finger 22 covers the second sensing area 122 simultaneously in a predetermined period of time, the first sensing area 112 and the second sensing area 122 outputs a start up signal to the processing unit 101. The processing unit 101 starts up. The electronic device 10 is unlocked and changed from the sleep state to the working state.
S501: the first sensing area 112 and the second sensing area 122 detect finger motions;
S502: the processing unit 101 determines whether the thumb 21 covers the first sensing area 112 and the index finger 22 covers the second sensing area 122 in the predetermined period of time simultaneously; if yes, the procedure goes to S504; if no, the procedure goes to S503;
S503: the processing unit 101 keeps the sleep state of the electronic device 10;
S504: the processing unit 101 starts up, and the electronic device 10 is unlocked and changed from the sleeping state to the working state.
Even though numerous characteristics and advantages of the present disclosure have been set forth in the foregoing description, together with details of the structure and function of the disclosure, the disclosure is illustrative only, and changes may be made in detail, especially in the matters of shape, size, and the arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
